' IMPRovl-:MENT IN FlREiPRoF ILLUMINATING-TILES.

Specification forming part of Letters Patent No. 145,182, dated December2,1873; application filed October 8,1873.

OAsn B.

To all whom it may concern: v

Beit known that I, THEoDoRE HYATT, of New York city, in the county ofNew York and in the State of New York, have invented certain new anduseful Improvements in Fire Proof Illuminating-Tiles; and do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference heilig had to the accompanying drawing making a partof this specification, in which- Figure 1 is a plan view of the upperside of my improved tile. Fig. 2 is a vertical section upon line w a' ofFig. 1, and Fig. 3 is a like view of the same, with its lower sideprotected by means of a metal casing.

Letters of like name and kind refer to like parts in each of theligures.

The design of my invention is to enable an illuminated roof to beconstructed of reproof material, and in a durable manner, at acomparatively small expense; and it consists in an illuminatingroofing-tile constructed of or from sheet metal, and covered beneathwith asbestus, made plastic and adhesive by the admixture of earthy orother suitable material, substantially as and for the purposehereinafter specified.

In the annexed drawing, A represents a sheet-metal plate provided,preferably, with a series of longitudinal corrugations or ribs, c, andhaving at suitable equidistant points upon or within its surface anumber of light-openings, a', which openings may have any desired shape,or form, or size. The plate A has any convenient size, and at its edgesis turned downward for about one-half an inch, after which said plate isplaced in a horizontal position, (bottom upward,) the lenses B areplaced over the light openings a', and the space around them illed withsuitable plast-ic lfire-proof material C, which latter is then permittedto set or harden. The plastic material employed, C, is composed ofasbestus finely ,subdivided and mixed with earthy or other tire-proofmaterial, which possesses sufficient adhesive properties to give to saidasbestus such cohesion as to enable it to maintain its position upon themetal plate.

If desired, metal studs D, having enlarged heads, may be attached to orupon the metal plate, and extend downward nearly to the line occupied bythe lower surface of the plastic covering, which latter, when applied,sur rounds said studs, and is more securely held in position. Theplastic material performs a treble office in this connection, theprincipal of which is the protecting of the tile-plate from injury byheat 5 the second, the. neutralizing of the heat-conducting qualities ofsaid tile, whereby greater protection is afforded to the building, andsweating is prevented during sudden changes of temperature; while,lastly, said material performs the ofiice of a cement, and firmly holdsthe lenses in pla-ce.

If desired, for the purpose of increasing' its strength or adding to thedurability or linish of the tile, its lower surface may be covered bymeans of a sheet-metal plate similar to that forming its upper side, butarranged with its ribs or corrugations at a right angle to those of thelatter, which lower plate may be secured at its edges to or upon theedges of said upper plate by solder or other suitable means.

The tile thus constructed is placed within suitable rabbets c formed inthe sides of the supporting-beams E, and a vater-tight joint made atsuch points by solder, cement, or other like material.

Having thus fully set forth the nature and merits of my invention, whatI claim as new 1s An illuminating-roofing tile constructed of or fromsheet metal and coated beneath with asbestus, made plastic and adhesiveby the admiXture of earthy or other suitable material, substantially asand for the purpose specilied.

In testimony that I claim lthe foregoing I havehereunto set my hand this7th day of October, 1873.

THEODORE HYATT.
